Abstract: Eleven ice model test programs have been conducted in a synthetic ice modeling material at the authors' company over the past two years, consisting of tests of ice worthy drillships, semisubmersibles, drill barges, conical drilling structures, and supply boats. This paper presents the properties data obtained from the forty ice sheets comprising those model test programs. The properties data obtained are compared to the available properties data achieved from the use of sodium chloride and carbamide (urea) doped refrigerated model ice, and the relative advantages and disadvantages of the three ice modeling materials are discussed. Particular attention is given to the impact of these available model ice properties on the selection of the scale factor, and to the effects that the scale factor and the ice modeling material will have on ice model testing capabilities as the thrust of ice model testing changes in the next few years to meet the needs of the petroleum industry for exploration and production in broad regions of the Beaufort Sea, the Chukchi Sea, and the northern and southern regions of the Bering Sea.
